Abstract
The invention discloses a kind of composite cooling flameproof motor rear end caps, including lid, flange, several gussets；Bearing hole is equipped in the middle part of lid；Flange is opposite with lid axially spaced-apart, by being evenly arranged on several link of boards of lid bearing hole surrounding together；Several cooling air channels are formed between gusset and lid right side, flange left side；Gusset is arc panel；Interlayer water channel is equipped in lid；Lid outer wall is equipped with water inlet interface, water outlet mouthpiece；Further improvement lies in that: gusset quantity is the odd number within 3~15；On the section by lid bearing hole central axis, for the cooling air channel formed between gusset and lid right side, flange left side closer to lid bearing hole central axis, axial dimension is bigger；Water inlet interface, water outlet mouthpiece circumferentially offset 180 ° of arrangements on lid outer wall.The present invention can be sufficiently cooled rear end cap middle (center) bearing, guarantee rear end cap middle (center) bearing normal use.
Description
Technical field
The present invention relates to technical field of motors, and in particular to a kind of motor rear end plate.
Background technique
Bearing is installed, rear end cap middle (center) bearing generates certain heat, shell to motor at runtime in motor rear end plate
A large amount of heat is generated in body, these heats can be such that rear end cap middle (center) bearing temperature increases, and influence the normal use of bearing.Therefore,
The motor rear end plate of the prior art takes certain cooling provision, but there are many heat that is very big for some load, generating
Motor, cooling capacity is still insufficient, can not be sufficiently cooled to rear end cap middle (center) bearing, not can guarantee rear end cap middle (center) bearing
Normal use.
Summary of the invention
Rear end cap middle (center) bearing can be sufficiently cooled, be guaranteed in view of the deficiencies of the prior art, the present invention proposes a kind of
The composite cooling flameproof motor rear end cap of rear end cap middle (center) bearing normal use.
The present invention is achieved through the following technical solutions technical goal.
Composite cooling flameproof motor rear end cap, including lid, flange, several gussets；Axis is equipped in the middle part of the lid
Bearing bore；The flange is opposite with lid axially spaced-apart, by being evenly arranged on several link of boards of lid bearing hole surrounding together；
Several cooling air channels are formed between the gusset and lid right side, flange left side；It is theed improvement is that: the gusset
For arc panel；Interlayer water channel is equipped in the lid；The lid outer wall is equipped with water inlet interface, water outlet mouthpiece.
In above structure, the gusset quantity is the odd number within 3~15.
In above structure, on the section by lid bearing hole central axis, the gusset and lid right side, flange
For the cooling air channel formed between left side closer to lid bearing hole central axis, axial dimension is bigger.
In above structure, the water inlet interface, water outlet mouthpiece circumferentially offset 180 ° of arrangements on lid outer wall.
Compared with prior art, the present invention having the positive effect that:
1, using air-cooled, water channel Compound cooling mode, rear end cap middle (center) bearing can be sufficiently cooled, is guaranteed in rear end cap
Bearing normal use.
2, gusset be arc panel, in this way, in the use of the present invention, in electric machine casing formed spiral shape cooling air channel, into
One step improves cooling effect, and more fully cooling, guarantee rear end cap middle (center) bearing normal use can be carried out to rear end cap middle (center) bearing.
3, gusset quantity is the odd number within 3~15, in this way, in the use of the present invention, irregular turbulent flow is formed, into one
Step improves cooling effect of the invention.
4, on the section by lid bearing hole central axis, shape between gusset and lid right side, flange left side
At cooling air channel closer to lid bearing hole central axis, axial dimension is bigger, and cooling air channel section also gradually increases, this
Sample can absorb more wind ginsengs and enter cooling air channel, further increase in the use of the present invention, generating certain siphonage
Cooling effect of the invention.
5, water inlet interface, water outlet mouthpiece circumferentially offset 180 ° of arrangements on lid outer wall, and cooling water is in water channel
The path length of process further improves cooling effect of the invention.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the A-A cross-sectional view in Fig. 1.
Specific embodiment
The invention will be further described below according to attached drawing and in conjunction with the embodiments.
Composite cooling flameproof motor rear end cap shown in the drawings, including lid 1, flange 4, several gussets 3；Lid 1
Middle part is equipped with bearing hole；Flange 4 is opposite with 1 axially spaced-apart of lid, by several gussets 3 for being evenly arranged on 1 bearing hole surrounding of lid
It links together；Gusset 3 is arc panel, and quantity is the odd number (in the present embodiment, 3 quantity of gusset is 11) within 3~15, muscle
1 right side of plate 3 and lid, flange form several cooling air channels between 4 left side；Interlayer water channel 1.1 is equipped in lid 1；Lid
1 outer wall of body is equipped with water inlet interface 1.2, water outlet mouthpiece 1.3, and in the present embodiment, water inlet interface 1.2, water outlet mouthpiece 1.3 are in lid
180 ° of arrangements are circumferentially offset on 1 outer wall.
On the section by 1 bearing hole central axis of lid, between 1 right side of gusset 3 and lid, 4 left side of flange
For the cooling air channel of formation closer to 1 bearing hole central axis of lid, axial dimension is bigger.
